AUTOMATIC DRAIN-PIPE COUPLING.

T 0 all "whom 2'25 may concern: I

Be it known that I, iv'lARTIN A. Banana, a citizen of the United States, residing at Cleveland, in the county offlnyahoga and State of Ohio, have invented certain new and useful Improvements in Automatic Train-Pipe Couplings, of which the following is a specification.

The present invention relates to automatic train pipe; couplings and more particularly to an interchange or adapter employed for the purpose of connecting the train pipes of a car not equipped with an automatic coupling to the coupler head of a car having such a coupling. The principal objects of the invention are to provide a simple interchange and an improved dependable means for securing the same to the head of. an automatic coupler. Other objects and features of novelty will be apparent from the description taken in connection with the drawings in which:

Figure 1 is a perspective view of an interchange constructed in accordance with this invention;

Fig. 2 is a side elevation of a coupler head with the interchange secured thereto;

Fig. 3 is a partial top plan view of the parts shown in Fig. 2; m

Fig. 4 is a side elevation of an automatic coupler head showing the socket and aperture employed in attaching the interchange thereto;

Fig. 5 is a bottom plan view of the coupler head shown in Fig. 4 illustrating the socket formed in the bottom of the head:

Fig. 6 is a front elevation of a coupler head with the interchangesecured thereto;

Fig. 7 is a side elevation of a pair of conpler' heads illustrating the manner in which the interchange apertures may be utilized as bolt holes to rovide an emergency support for one of (he heads in case its supporting means should fail.

Referring to the drawings the reference letter A indicates an automatic coupler head which is shown of substantially the form disclosed in my Patents 1.161.403 and 1,161.372, although it is understood that the invention is not limited to this })2I1'ti(3lll;11-

construction of coupler head but maybe employed with other forms than that shown. As illustrated the head has the usual conduits 10. 11 and 12 for the air signal, air brake and steam pipes, respectively.

Serial N0. 249,1$3.

In the face of the head tlrese co -(h:('its have the usual gaskets 13, 14 and 1:3,which project slightly from the said face.

The interchange comprises a plate 16 having the conduits 18 and 19 which are provided with the couplings 20 and 21 adapted for connection to train pipes in the usual manner. The interchange is constructed to IJC positioned against the face of the coupler head with the gasket 22 of conduit 18 and gasket 23 of conduit 19 in register with the gaskets 13 and 11 respectively of the head. The interchange here shown is adapted for use with freight cars and hence has no conduit. corresponding totthc steam pipe conduit of the coupler head, the plate 16 acting as a blind flange to close the conduit 12 in the head. It is to be understood. however,

that the interchange may be pr'u'ivided with a.

steam pipe connection in.addition to the others when it is employed with passenger cars or cars having a steam pipe. One side of the frame 16 is formed with the recesses 21 and 25 so that it may be secured to the coupler head without interfering with the projecting guide 26. Obviously, the form and propoition of the plate may be varied to suit other types of coupler heads.

One of the important features of this invention consists in the means for removably securing the interchange to the coupler head. For this purpose, on one side of the interchange, shown as' the bottom side, is formed a bent or hook shaped pin 27 which projects in front of the face of the plate 16. The top of the plate, or the. side opposite the one having the projecting pin, pivotally carries an arm 28, the pivotal mounting consisting of a pin 29 extending through the arm near one end thereof and carried by the spaced ears 31, 32, the arm being mounted on the pin between these cars. This arm near its free end is formed with a slot 32 extending transversely therctln'ough, for a purpose presently to be described.

In order to carry the interchange, the head is formed with a projecting lug at the bottom thereof, this lug comprising spaced substantially parallel side walls 33 and 3% connected by a wall 35, the front of which is flush with the face of the coupler head. This latter wall is formed with an aperture 36 extending therethrough and opening into the space between the parallel walls and 34, thus forming a socket for the pin 27 on the interchange. At the top the head has a lug i'llwhich is'formed with an aperture 38 eitcnding therethrough of asize to receive the arm 28 on the interchange. In applying ...an .interchangejto a coupler head, the in 2'? of the former is inserted and held in t e socket]; 36; of the latter and 'then'the arm 28 is thrust through the aperture 38 in a the top of the heat? and the tapered pin 39, 1

attached to the interchange as by means of the-flexible connector 40, is driven in the slot 32* of the arm, one side of the pin hearing against the lug 37 on the head and the other bearing against the opposite end wall of the slot. As the taper of the pin is slight.

it will be seen that not only is the interchange drawntightly against the face of the head but the pin will be held securely by the frictional contact with the lug 37 and the end wall of the slot in the arm.

In addition to providing means for sup porting the interchange the apertures 36v and 38 of the coupler head may also be employed to make an emergency connection between a pair of coupler heads, in case the support" for one of the heads" should fail.

This use ofthe apertures isTillustrated in Fig. 7. Of course if thesupportingmeans for one of. the automatic cou l'er heads should break the train would v until the train pipg s could be connected up ith the present gen ral-c tion a very quick emergency connection-can e held up in some manner.

be made merely by inserting 41 through the apertures 36 andBS "tlf" mat! ing coupler heads asclearlyshown.Y'Thus the unsupported head will be carried by the uninjured one and the train may 'roce'ed, having been delayed onlyforthe ew m0- ments required to insert the bolts through the said a. ertures.

. Althoug an embodiment of the invention has been described inv detail, itis to be uninterchange tightly against the face of the? derstood that the invention includes other forms within the scopaof the appended claims. i
